Abstract: The gas and light barrier properties of a web ofthermop- lastic bags designed for aseptic packaging are improved by laminating a material of high gas and light imperviousness, such as metal foil, to the thermoplastic bag material during a blown film extrusion process. In one embodiment a pair of foil laminates (26) are applied to opposite sides of an inflated tube (16) by rollers (22) which flatten the tube to provide flat surfaces (24) for the laminates being applied to the tube. The resulting laminated web has a pair of aligned, uncovered longitudinal portions (32) along the centre of which a slit-seal may be made to provide a pair of laminated webs each having an uncovered longitudinal edge. In another embodiment a single sheet of foil having a width less than the full circumference of the tube may be employed to provide a single web having a longitudinal uncovered section.

Abstract: A device for fitting an attachment to an endoscope ocular section comprises a cylindrical receptacle (10) which is set in the endoscope ocular section (5) and has an end face (17), an adapter (7) which is set on the ocular section attachment (6) and fitted around the cylindrical receptacle (10) by rotation, a coupling ring (16) which is rotatably set in the adapter (7) and has an end face (16c) capable of being pressed againstthe end face (17) of the cylindrical receptacle (10), and connection mechanism (24, 25) for connecting the coupling ring (16) and cylindrical receptacle (10) together in a state prevented from being moved relative to each other. Provision of the connection mechanism prevents the end faces (17, 16c) of the cylindrical receptacle (10) and the coupling ring (16) from sliding over each other, thereby eliminating the possibility that a coeliac observation is obstructed by the appearance of a gloss on the end face (17) of the cylindrical receptacle (10) due to its rubbing.

Abstract: To avoid loss of temperature of a melt contained in casting ladles in a continuous casting operation, an independently rotatable platform adapted to receive a heating device is disposed on a slewing column of a slewing tower for ladles. The heating device is similar to that of an arc melting furnace and comprises a vertically adjustable electrode holder of outrigger configuration whose guide column is arranged eccentrically on the platform so that a current carrying cable can be installed to extend centrally through the platform and through the slewing column. The cables are secured by a clamping plate at a perpendicular distance from the platform, such that the electrode holder, as seen from the casting position, can pivot in both pivoting directions through approximately 180 DEG , without the cable tearing as a result of twisting.

Abstract: Process for the concentration of fibrous material in a mixture thereof with non-fibrous material, by causing an aqueous suspension of said mixture to flow upwardly to bring about settling out of material of reduced fibre content and formation of a fibre-enriched fraction above it, which is then separated. 
     In the process, the upward flow is made substantially non-turbulent, and is carried out with gas bubbles passing upwardly through the suspension, to increase the efficiency of separation of fibrous from non-fibrous material. 
     The process is specially applicabletothe concentration of fibres in the fibrous product (mineral wools) formed by disintegrating silicate and like mineral melts, which commonly contain a relatively high proportion of granular material ('shot').

Abstract: A method of increasing the cross-flow filtration flux of a suspended solids laden liquid through a porous filter tube wall comprises the steps of: (a) flowing the liquid through the filter tube and permeating the liquid through the tube wall by establishing a transmembrane pressure within the tube, thereby depositing at least a portion of the solids on the inner surface of the tube as a sludge layer; (b) periodically reducing the transmembrane pressure to about zero for periods not in excess of about 2 minutes thereby periodically permitting enhanced erosion of the sludge layer so as to reduce its thickness; and (c) re-establishing the transmembrane pressure after each intermittent reduction, whereby the time-averaged filtration flux is increased. Typically, the transmembrane pressure is established by creating a net positive pressure within the filter tube, and the periodic reduction of the transmembrane pressure is achieved by periodically reducing the net positive pressure to about zero. 
     Also disclosed is a method of increasing the cross-flow filtration flux of a suspended solids laden liquid through a porous filter tube wall, comprising the steps of: (a) flowing the liquid through the fitter tube and permeating the liquid through the tube wall by establishing a transmembrane pressure within the tube, thereby depositing at least a portion of the solids on the inner surface of the tube as a sludge layer; (b) periodically increasing the circulation velocity of the liquid flowing lengthwise through the fitter tube to a value in excess of about 7 fps, preferably between about 10 and about 20 fps, and more preferably to about 15 fps thereby permitting enhanced erosion of the sludge layer so as to reduce its thickness; and (c) reducing the circulation velocity after each intermittent increase, whereby the time-averaged filtration flux is increased. 
     Apparatus is also disclosed for practicing the methods of the invention.

IPC: C23G3/00

Abstract: The invention relates to the pretreatment of ductile non-ferrous metal to be deformed in a continuous plastic deforming device (20) in which the surface parts of the metal to be deformed do not substantially form surface parts of the metal after said deformation. Known methods of pretreatment include scaling off of thin surface layers and pickling e.g. in baths and coiling or storing the metal thereafter before feeding to the deforming device. Such methods have disadvantages in view of energy, waste of material and, in many cases, in still having some surface contamination on the metal entering the deforming device. To avoid such disadvantages, the invention proposes to spray the metal with a deoxidation and cleaning agent in one throughgoing operation directly while it is moving to the deforming device and continuously and synchronously therewith. Spraying is done by directing forceful jets of the liquid onto the moving metal surface. The spraying agent is a strong alkali and for some types of alloys there is a further spraying step using an acid such as a strong nitric acid solution in water. The metal is thereupon, while moving on to the deforming device, rinsed with water and dried.

Abstract: A heat exchanger comprising a plurality of plates (5, 6) arranged adjacent to each other, whereby passages (9, 10) for two mutually heat exchanging fluids are formed between the plates. The plates comprises corrugations or ridges (7, 8), whereby the corrugations form an angle (a) with the longitudinal rim of the plate. In the first type of plates the corrugations form a first angle (α<sub>1</sub>) with said rim and in the second type of plates the corrugations form a second angle (a<sub>2</sub>) with the rim. The plates are combined in order to form two types of passages having different thermal length. The firsttype of passage (9) is obtained by combining a first plate and a second plate and the second type (10) of passage is formed by combining a first plate and a second plate, wherein one of the plates is turned 180° in its own plane. Thus, two types of passages having different thermal lengths are obtained. The two types of passages can be combined for each heat exchanging fluid in order to provide the desired thermal length for that fluid.

Abstract: Apparatus for reducing the noise immunity of a tone selective receiver to prevailing noise conditions in a mains network, through which signalling takes place between a network unit and a plurality of terminal units subordinated to it, all of which are connected to the network. The tone selection circuit 3 sends a data flag signal DF, the duration of which is measured in a first time measurement circuit. If this duration is short relative the duration ofthetone ofthetransmitted tone signal, more and more capacitors are connected into an intergrating circuit 7 included in the tone selection circuit. The integrating circuit 7 thus determines the noise immunity of the tone selection circuit, until short-duration DF signals are no longer detected. The invention includes the use of a large number of capacitors Ci-C2n in the integrating circuit. In a corresponding manner the capacitors are disconnected stepwise each time a second time measurement circuit has determined that no interference has occurred during a given predetermined time period following the connection of a new capacitor into the integrating circuit.
